Coal-separator



in ordert adapt the Inachine for dierent Sizes aand qualibies of ooal. In operation the 00al is dep0sited upon the upper perf0rated plate 11 either upon the screen 10 or in any other nnanner atl(1 it Slides down upon the feed Wheel. The func tions Of the feed vvheel are t0 trnSfer the 00al froIn the upper )la'te t0 the separting p1te, and t0 aid in spread`ing the 001 int0 a thin layer upon the latter plate. By giving the feed whee1 the proper Speed of r0tation, the coal will be thrown With Some for06 upon the upper perforated plate 6 thus shaking Some Of the adhering dirt from it Which SiftS throu h the late and giving the slate nd Goal an impetus Which greatly adds t0 the efficienoy Of the Seprating plate. In prctiGe the Wheel hr0WS the coa1 upon the separa't in late and Starts it r011in down the in` cline just aS if it were thrown by hand or Shovel, an(1 the vel00ity thus acquired iS SL1E- Hoient '0 0arry it 0ver the flatter 1Ower Sections 0f the Separting i[[cline and ont0 the 10Wer inclines 21 22. The Slate however, on a000unt of its flat for[nation andgreater Spe 0iH0 grvity, slides a10ng he Separating plate and drops through the 0pening between Said plate and the 10Wer incline 21- EOI' aIly partioular grde 0f 001 the Inovable plate 21 can be Set by th eye after the c0a1 is Started, S0 as t0 Separte out the Slate The larger grades of ooa1 Will of oourse gin reater momentum and jum over a reater opening than the smaller grades, and there fore, for the snlaller sizes the 0pening Inust be less than for the larger.

Ib will be evident that various changes in the pr0portions and lllinor defails of oon- Struction may be made without departing from the spirit of ny invention. Ih11s, for

instance, it iS not abs01ute1y essential that the feed wheel should have blades, as shown, for it Will be evident that any construction having teeth or cavities which will receive and transfer the coa1 Would answer the pur- I)0Se.

Therefore, with0u1imiting myself t0 the exact constructi0n and rrangement of parts shown and described, I Olain1 1. In 00al separat0rthe combination '7ith thein01ined separating pla[1e of a feeding and Starting Whee1 arranged acr0sS the up per end of the p1ne and having blades 01' paddles for throwingthe c0al upon Said plane, and means for delivering e0al t0the feed Whee], subStntially as described v 2` In a 001 S6part0r the 00mbination vvith the inclined fricti0nal Separating plane of a the upper end of the pla.ne and having blad6s Or paddles for throwing the c0a]1 thereon, 0f
